ARTHUR ASCII-I, OF HAMBURG, GERMANY.

FLEXIBLE OCCLUISIVE PESSARY.

To all whom it may concern.

Be it known that I, ARTHUR AsoI-I, Med. Dr., a subject of the GermanEmperor, and resident of No. 54 Billhorner Rohrenda-mm, Hamburg,Germany, have invented certain new and useful Improvements in orRelating to Flexible Occlusive Pessaries, of which the following is aspecification.

The invention relates to an occlusive pessary for women, which is notintroduced into the mouth of the womb, but is clamped around the neck ofthe womb and may be worn permanently without causing inconvenience.

According to the invention the occlusive pessary consists in a doubletube of soft rubber or the like, which embraces the mouth of the womb,while in the acket formed by the tube a flexible stiflening frame isprovided. The pessary rests with its upper edge against the vagina. Atits lower end it is provided with a valve cap, the ducts of which areclosed by a double acting valve either from the outside or from theinside.

The drawings show-by way of example such a pessary embodying theinvention on an enlarged scale.

Figure 1 is a vertical section and Fig. 2 a plan of the completepessary, while Fig. 3 shows the stiffening frame in vertical section andFig. 4 the same in plan.

The stiflening frame, composed of steel wire, consists in a large ringon and a smaller ring a, which are connected by stays 79. Both, therings m, a, as well as the stays p are totally or partially formed byhelical springs, so the whole frame, which has the shape of a truncatedcone, is flexible in every direction. In the constructional exampleshown in the drawings, the stays p are formed in their upper parts, toabout one fourth part of their length, of solid wire, while their lowerparts extending down to the lower ring a are constructed as helical wiresprings, so that the frame at its upper end oifers suflicient rigidityto the hand, which introduces the pessary into the womb pipe.

Radial arms or supports 9, directed inwardly, are arranged on the staysp and carry pressure plates or pads it. These radial supports 9 also arepreferably made in the form of helical springs. The whole frame isinclosed inside the pads u and outside the stays p, by the tube orflexible casing a, whose ends meet on the exterior cir- Specification ofLetters Patent.

cumference of the valve-cap Z). The inner end of tube a is securelyclamped on valvecap Z) by means of the ring a of the stiflening frame,while the outer end of tube a is secured on the valve-cap b, by means ofspecial wire-binding. This latter end of tube a is hereby drawn over thering a of the stiffening frame, so that the latter is completelyinclosed within the double tube. For this purpose the valve-cap b isexteriorly provided with two flanges between which the ends of the tubeand ring a of the stiffening frame, embrace the valve-cap b. This cap iscentrally aperturedfor the accommodation of the stem of a duplex puppetvalve (Z, which passes loosely through the aperture and carries a diskat each end, one of said disks being located on the outer side of thevalve cap, while the other disk is located on the inner side of saidcap.

The double acting valve (Z closes by means of its two disks, either fromthe inside or from the outside, according to its position, the ducts 0in the valve-cap I) while in its middle position it allows easy accessto douches and injections, so that the pessary need not be removed forthe purposes of such operations.

The valve (Z as well as the valve-cap Z2 may be produced of metal orother suitable material. If metal be employed it is advisable that thevalve and valve-cap, as well as the wire frame should be nickel platedor otherwise protected from corrosion.

What I. claim is 1. A pessary comprising a flexible tubular casingadapted to embrace the mouth of the womb and rest with its upper endagainst the vagina, a flexible stiffening frame within the casing, anapertured cap provided with a port and arranged on the lower side of theframe, and a duplex puppet valve having a stem that passes looselythrough the apertured cap and carries a disk at each end, one of saiddisks being located on the outer side of the valve cap, while the otherdisk is located on the inner side of said cap.

2. A pessary comprising a flexible tubular casing adapted to embrace themouth of a womb and rest with its upper edge against the vagina, aflexible stiffening frame within the casing, pressure members extendinginwardly from the frame and engaging the inner portion of the tubularcasing, an apertured cap provided with a port and arranged on the lowerside of the frame, and Signed by me at Hamburg this fourthday a duplelxpuppeti1 valve halving a stem:1 that ofDec. 1912.
